` SHIP CONSTRUCTION.

Application led November 20, 1926. Serial No. 149,666.

This invention relates to-steel ship construction. The invention may also be advantageously followed in constructing tank tops or side tanks, such as are now in use on vessels of the Great Lakes.

Itis contemplated to form the ships from steel channel members which can be so arranged as to run vertically, transversely or longitudinally of the ship. The. channel members may also form collision and watertight bulk-heads as well as the deck and flooring for the ships or dry-docks.

An object of the invention is to provide a ship hull constructed entirely of channel members.

Another object is to provide a ship hull wherein a minimum number of rivets will be exposed upon the outside of the hull.

Other objects and advantages will hereafter appear.

An embodiment of the invent-ion is illustrated in the accompanying drawing wherein Figure 1 shows a number of the `channel 'members in section having the angle clips secured thereto for the frame fastenings.

Figure 2 is a sectional view showing the method of attaching the transverse channels to the longitudinal channels.

Figure 3 is a sectional view showing the manner in which the water-tight fastenings for the transverse bulk-heads are obtained. v

Figure 4 is a detail view.

Figure 5 shows general outline of a barge constructed in accordance wtih the invention. f

Figure 6 is a sectional view showin method of fastening the water-tight heads to the channels.

Figure 7 is a. general outline of a barge showing a sectional detail view of the corner the ulkchannel, and

Figure 8 is a detail view.

In general, the ship is constructed of a plurality of channel members 1. These members are secured together by bolts, rivets or other means passed through the adjacent ianges thereof. The channel members 1 are formed according to the style of boat under construction. Those shown in Figure 1 have their transverse web portion straight, while those shown in Figure 2 have their transverse web mined arc.

In order to fasten cross frames and the like 2 t0 the channels, a clip member 3 is employed. This clip member comprises an portion formed on a predetering the frame. It will be apparent that this arrangement reduces the ynumber of bolts or rivets passing through the hull of the boat.

In constructing certain types of vessels, it is necessary to use transverse channels as well as longitudinal channels. Figure 2 shows a vessel so constructed wherein angle iron 8 is riveted or otherwise secured to the bottom of the member 7. The rivets passing through the member 7 to the outside of the hull presents the only instance in the entire construction wherein any bolts will be eX- posed upon the outside of the vessel. To the vertical side of the member 8 the flanges of the first transverse channels may be attached.

Figures 5 and 6 disclose the method of fastening water-tight bulk-heads between the channels. This method consists in riveting a bulk-head 9 between the flanges of a pair of adjacent channels l. This bulk-head preferably consists of a single sheet of material and will advantageously prov-ide longitudinal bulk-heads through the main body of the boat, as well Ias cross bulk-heads in the bow or stern where the channels are lto run transversely.

In Figures 3 and 4 the manner of fasteningl transverse bulk-heads to :the channels is shown. A channel or angle iron 10 is cut out to it the entire space between the flanges of the boat channels and may be electrically welded or otherwise fastened to such flanges. Secured tothe member 10 on the horizontal side thereof is a second angle 11. This angle is preferably riveted to the angle 10 while the bulk-head 12 is secured to the vertical side of the second angle.

' In practical operation, the bulk-head and the angle attached to it are assembled before being put into the boat. members may be readily fastened to the irst angle Ywhich has. already been welded or otherwise secured in place.

In a -vessel constructed of the chlannel members, means must be provided which will eiiiciently form the corners of the vessels. Such means is shown in`Figures 7 and 8, wherein rolled channels ,13 are utilized for' the corner. These channels consist simply of a curved channel member wherein the These assembled i flanges y14 and 1 5 thereof are bent at the proper angle for fastening thereto the channels which form the sides or deck of the boat.

The channels just 'described may be used for bilge plates, for the edges of the deck, or for the corners of the boat at the bow and stern.

It should be understood, of course, that suitable gaskets may be placed in the construction, wherever needed, between the flanges of the channel members, and that these gaskets may be of any form such as wood, cork or felt. Of course, in place of a gasket, a layer of ordinary lead paint could be used. I

From the foregoing description, it will be clear that the various parts set forth therein will enable the construction of a vessel to be carried out in which the entire hull, together with the transverse frames, deck, or bulkheads, will be formed of channel members.

This construction would cost considerably f less than the usual constructions now fol- Cil the said claims.

lowed and will also enable a vessel to be constructed more quickly. Y.

Having described in detail an embodiment of the invention, the following claims are appended hereto with the understanding that the invention is susceptible of many variations and adaptations Within the scope of What I claim is:

1.' A shi construction comprising channel members orming the ship hull, having inturned flanges, said channel members being connected together by securing means passing through adjacent flanges of adjacent members, a flanged member extending trans versely 4Within the first named channels, an angle member arranged upon and secured to said flanged member, so as to have one flange thereof projecting upwardly, whereby a bulk-head may be secured to said up- Wardly projecting flange.

2. A ship construction comprising channel members forming the hull, having inturned flanges, said channel members being connected together by securing means pass-l ing through adjacent flanges of adjacent channel members, angle membersadapted to have one arm thereof secured tothe flanges of the channel members by the securing means connecting the adjacent flanges and the other arm thereof extending at substantially right angles to the first arm and adapted to have elements forming the frame braces attached thereto, whereby the passage of securing means through the hull to the outside is eliminated, angle members cut to lit withinthe first named channels and secured thereto, angle members so arranged upon and secured to said last named channel lmembers as to have one flange thereof projecting upwardly, whereby attaching portions for bulk-heads are provided.

8. A ship construction comprising a hull formed of channel members having their adjacent flanges secured together, angle members connected to the adjacent flanges of the channel members by the means securing the said flanges together, said yangle members having one arm thereof extending in the same direction as the flanges and the other arm thereof@ extending parallel to the web .portion of the channel members, whereby BERNARD S.
